I have been tasked also to do a low jitter PLL in 130nm. You can't quite get there with a Ring VCO unless you burn tens of mA in VCO current. You will probably need a spiral inductor osc with thick top layer metal.
I am using Cadence ADE and would like to define an output variable then re-use it within another output description. How do I do this? I know I can use a Design variable such as VDDA using: VAR("VDDA"). But how do I re-use an output variable name?
